Thank O/C, and he is correct, 4 fans are Blue LED fans.
The two at the top and one on the side panel are ball bearing 120mm fans with fan controller knobs at the back as shown in the pics. The can be turned up to do some serious RPM and make some noise when you benching or something and at the same time be near silent running at min speeds.
The 4th fan is at the front to cool the HDD bay, dunno if it's a ball bearing or not but it works fine and has outlived 3 sleeve bearing fans I bought initially for the case.....
Of course there is the normal black exhaust fan that you see sending air out the back of the case in the fourth pic.
So the case actually has 5 fans in it, 4 of which a Blue LED Cooler master fans. 3 of which I bought that are ball bearing fans with fan controllers.
I aint see any better deal than that.
